Watering System for Soil?

Was wondering if someone had any ideas for a watering system. I am a medical grower with only one patient who is just finishing my first grow. Everything has gone well and I am getting ready to bring my first harvest in. I will be upping my patients from just myself to 4 total which means I will be growing 48 plants in soil this winter. That will be alot of watering and was looking for some ideas on how to make watering easier. Thanks for any help you all can offer.

I run a drip to waste system at our collective. Very simple.

Reservoir > water pump > Water lines > waste reservoir or outside

Im sure there's some more detailed threads in the hydroponics sections.
